2 CHOReVOLUTION Title: Automated Synthesis of Dynamic and Secured Choreographies for the Future Internet Follow up FP7 EU project CHOReOS Period: January 2015 - January 2018 Site: http://www.chorevolution.eu
3 Outline Setting the context Approach 則 Adapter Metamodel 則 Rule-based Adapter Generation Case Study Adapter Generation at work
4 Setting the context
5 Service choreographies Choreography (fully distributed) Global decentralized view from a multi-participant perspective (without a central controller)
6 Choreography realizability enforcement Automatic realizability enforcement: given a choreography specification and a set of existing services to be reused, externally coordinate their interaction so to fulfill the collaboration prescribed by the choreography specification coordination and adaptation issues must be solved automatically automatically compose services, and perform exogenous coordination and adaptation of their interactions (nontrivial and error prone)
7 BPMN2 choreographies Task in BPMN2 - atomic activity - two participant roles (one is initiating) - XML Schema used internally, e.g., for discovery purposes Parallel flow - Diverging Parallel Gateway - Converging Parallel Gateway Alternative branches - Diverging Exclusive Gateway - Converging Exclusive Gateway
8 CHOReVOLUTION synthesis process Binding Components (BCs): are generated when the middleware- level interaction paradigm of a selected service is different from SOAP, which is used by as the middleware-level interaction paradigm Security Filters (SFs): are generated for those (selected) services having security constraints Adapters (As): allow to bridge the gap between the interfaces and interaction protocols of the selected services and the ones of the (respective) participant roles they have to play and solve possible interoperability issues due to operation names mismatches and I/O data mapping mismatches Coordination Delegate Generation(CDs): are in charge of coordinating the interactions among the selected services so as to fulfill the global collaboration prescribed by the choreography specification, in a fully distributed way

1 1 Approach Model-driven approach: Adapter metamodel Transformation rules Subset of Enterprise Integration Patterns (EIPs) [1] Flow-driven adaptation Data-driven adaptation [1] - Gregor Hohpe and Bobby Woolf. 2004. Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions - Fiftheenth printing 2011. Addison- Wesley Longman Publishing Co., Inc., Boston, MA, USA.
1 2 Flow-driven adaptation Flow-driven adaptation: is realized by means of Message Routing EIPs and it is used to adapt sequences of messages; this type of adaptation operates at the granularity of messages, without touching the content of the messages
1 3 Data-driven adaptation Data-driven adaptation: is realized by means of Message Transformation EIPs and are used to adapt the content of a single message exchange; this type of adaptation operates at the granularity of the data items constituting the message and their types

2 3 Smart Mobility and Tourism choreography
2 4 Adapter Generation at work
2 5 Smart Mobility and Tourism choreography Regarding Smart Mobility Information one of the involved participant is the Journey Planner participant, who is in charge of providing trips information to the Mobility Information Planner The two participants exchange the messages tripsRequest and tripsResponse within the choreography task Get Trips Information.
